Team Q4 and friends have a Vanguard training camp at a beach, but they`re surprised to meet the powerful team that actually invited them. Will Aichi and his teammates actually learn and improve, or be distracted by fun-in-the-sun beach activities?!

Dissatisfied with the training camp, Kai goes to the wrong side of the tracks for an edgier kind of Cardfight. Kai gets what he wants and then some, going up against the King of Underground Fights, with Miwa as a hostage!
